UNS8 buildPDO	(	CO_Data *	d,
		UNS16	index
	)

Prepare the PDO defined at index to be sent by PDOmGR Copy all the data to transmit in process_var *pwCobId : returns the value of the cobid. (subindex 1) Return 0 or 0xFF if error.

UNS8 PDOmGR	(	CO_Data *	d,
		UNS32	cobId
	)

Prepare a PDO frame transmission, whose different parameters are stored in process_var table, to the slave. bus_id is hardware dependant call the function sendPDO return the result of the function sendPDO or 0xFF if error

UNS8 proceedPDO	(	CO_Data *	d,
		Message *	m
	)

Compute a PDO frame reception bus_id is hardware dependant return 0xFF if error, else return 0

UNS8 sendPDO	(	CO_Data *	d,
		s_PDO	pdo,
		UNS8	request
	)

Transmit a PDO data frame on the bus bus_id pdo is a structure which contains the pdo to transmit bus_id is hardware dependant return canSend(bus_id,&m) or 0xFF if error request can take the value REQUEST or NOT_A_REQUEST

Transmit a PDO request frame on the bus bus_id to the slave. bus_id is hardware dependant Returns 0xFF if error, other in success.
